[NTG-context] Can't find CFF table, not related to extension

Hi, I get this error with a font I just downloaded. It's my first attempt at using a font not provided with context minimals: %% !luaTeX error (file /home/mauricio/fontes/TITUSCBZ.TTF): can't find table `CFF ' ==> Fatal error occurred, no output PDF file produced! %% I found a thread on the mailing list discussing this, but the problem seems to have been solved by changing the extension to .TTF, but my file was already TTF when I first saw it. Thanks for your help, Maurício
